Laryngeal cancer is a common malignant tumor in everyday life. In the early stages, patients with laryngeal cancer usually experience symptoms such as hoarseness, coughing, and a foreign body sensation. In the middle and late stages, patients may suffer from breathing difficulties or even choking, as well as swallowing difficulties. When symptoms of laryngeal cancer appear, we should initially complete examinations with an electronic laryngoscopy, laryngeal CT scan, and pathological biopsy to determine the pathological type of the patient, to confirm the diagnosis. At the same time, we should pay attention to a light diet, primarily warm, cold, and semi-liquid foods, and avoid smoking and drinking alcohol. Additionally, we should detect tumors early and treat them promptly through surgery.
